Specification of Letters Patent.

Patented Feb. 6, 1917.

Application filed August 3, 1914. Serial No. 854,708.

To all whom it may concern:

Be it known that I, EDGAR E. PHINNEY, a citizen of the United States,resident of New York, in the county of New York and State of New York,have made a certain new and useful Invention in Carrying Mechanism forCalculating-lVIachines; and I declare the following to be a full, clear,and exact description of the same, such as will enable other skilled inthe art to which it appertains to make and use the invention, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

Figure 1 is a section on the line 11, Fig. 2, with the slide top of thepivoted arm in normal position.

Fig. 2 is a section on the line 2-2, Fig. 1.

Fig. 3 is a detail side view of one of the pivoted arms and partsadjacent thereto, showing the slide top moved back slightly in the extramovement of the numeral wheel under momentum thereof.

Fig. 4 is a similar detail view showing the pivoted arm in depressedposition.

Fig. 5 is a detail top plan view of oneof the pivoted arms with theslide top thereof removed.

Fig. 6 is a detail side view of the same.

Fig. 7 is a detail side View of one of the slide tops.

The invention has relation to calculating machines, and particularly tothe carrying mechanism thereof, having for its object certainimprovements upon the machine of the patent to Baldwin of December 2,1913, Number 1,080,245,to provide for easier working and more positiveaction.

The invention consistsin the novel construction and combinations ofparts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 18designates the numeral wheels of the registering mechanism, 12 theintermediate gears, 78 the shaft of the carrying mechanismand j, thepivoted dogs of the carrying mechanism. In place of the reciprocating ordepressible plungers p, of the patent, pivoted members or arms 14: areprovided between the gears 12, said members being mounted upon a 1011-gitudinal shaft 15 of the casing. Each pivoted arm has an upper camextension 16, engage'd y th OQth g, of. the numeral wheel 'by the springlatch.

corresponding thereto, to depress said member upon its pivot, a springlatch 18, mounted in the shaft of the intermediate gears and engagingteeth or notches 19 of said member, acting to releasably hold the memberin raised or in depressed position.

In the registering operation of the machine, impulse will be transmittedthrough gears 12 to the gears of the numeral wheels 13, according to thenumbers selected, by means of the devices described in Patent No.1,080,245, hereinbefore referred to. As any one of these gears 13 passesfrom nine to zero or from zero to nine the lateral tooth extension 9thereof is caused to engage with the upper cam extension 16 of therespective pivoted arm below the same, this arm being forced down uponits pivot to the lower limit of its movement, or until the spring latchengages with the upper notch 19, a lower cam lug 20 of the arm beingthus depressed so that it will lie within the path of movement of thecorresponding dog j.

The registering operation being complete, and the carrying shaft havingrotated to initial active position, further rotation of said shaft willbring a dog j into contact with the cam lug 20 of any arm lat depressed,said dog being thereby thrown so that the end j of the dog will projectin position to engage and turn the next intermediate gear 12 to the leftthereof, and also the next numeral wheel 13, one tooth only, at the endof which time the pivoted arm will be raised to normal position by a camt, upon the radial dog carrying arm, where it will be held The lower camlugis beveled oppositely at the ends thereof, so that it will throw thedog in either direction of rotation.

It is preferred, for reasons hereinafter set forth, that the upper partof each carrying arm, upon which is the cam extension 16,

shall be separate from the arm proper, being arranged as a slide top 16for the arm, with which it has pin and slot connection 21, the slide topbeing provided in rear with a cam surface 22, which, as the slide isfirst forced back in the engagement of the cam extension thereof withthe tooth g, of the gear, will have contact with a bar 23 of thecarriage casing, to force the carrying arm down. A return spring 21 isprovided for the slide top. In this way, when the slide is moved back afraction of an inch to engage said shaft, the tooth will have contactwith the beveled surface 16 of the cam extension 16, to force thecarrying arm down, and the cam surface 22, in rear of the slide, willhave contact with the bar 23 to insure the downward movement.

When the machine is operated at high speed, the numeral wheels 13 areliable, through momentum, to take a slight ext a movement in excess ofthe gear movement imparted, and, should this take place in a wheel aboutto pass from nine to zero or from zero to nine, there is danger that itstooth Q will strike the cam extension 16 of the carrying arm 14 withsullicient force to throw said arm into lowered position, thus carryinga number impri'iperly to the next wheel. to the left. 7

in order to obviate this (fliliiculty, the car rying arm 1 is so placedthat the lateral tooth I in the position assumed by this tooth when thewheels 13 indicate the number nine, is spaced apart from the camextension 16 by a distance {0, sufhcient to allow for the movementreferred to, when the wheels 13 are turned at high speed in a directionfrom nine to 0. Nhen turning in the reverse direction, however, thedistance y, between the cam extension and the tooth g, in the positionassumed by this tooth when the wheels 18 indicate 0, is less than thedistance a1, and insuliicient to allow for the movement, which will nowbe taken up by the slide top.

But when it is necessary that the carrying arm shall be operated by anumeral wheel in passing from zero to nine after the slide top has beenmoved to the extent permitted, the relation of the tooth g, and the camextension 16 as shown in Fig. 3 will be such that some additional meansare desirable to depress or insure the depression of the carrying arm,and it is for this reason that the cam surface 22 of the slide hasengagement with the bar 23.

What I claim is i. In a calculating machine, a carriage having a seriesof numeral wheels, a series of gear wheels in operating engagement withsaid numeral wheels, and carrying mechanism comprising a rotary shafthaving carrying members, and depressible pivoted carrying arms operatedby said numeral wheels and having engagement with said members, andmeans for allowing extra movement of the numeral wheels when suddenlychecked, without depression of said arms. 1
